Actor-turned-TV presenter Mario Lopez is set to become a dad again. The former Saved by the Bell star and X Factor host has announced his wife Courtney is pregnant with a sibling for the couple’s two-year-old daughter Gia. Mario tells news show Extra, which he co-hosts, “I am the happiest father in the world. We cannot wait to welcome baby Lopez number two into our lives.” Extra cameras caught the big reveal on film on Tuesday morning and staged a surprise baby shower complete with balloons, guests and gifts. Little Gia appeared holding a sign that read: ‘I’m gonna be a big sister’. Lopez wed Courtney in December in Punta Mita, Mexico.
